Abstract The acid activation process increased the specific surface area of raw Resadiye bentonite (33.5 m2/g) by ∼ 4-fold whereas the interaction with n-butylamine caused a surface area reduction of acid-activated bentonite by 40% along with the broadening of the Si-O stretching peak at 1041 cm−1 and the decrease of the d001 value from 14.5 to 13.5 Å. The thermal analysis data confirmed the stability of the mesoporous n-butylamine/acid-activated bentonite composite up to 499 °C which was followed by the cleavage of the interlayer n-butylamine species between 500 and 700 °C.

丁胺-resadiye膨润土复合材料表征

摘要 酸活化过程使原始 Resadiye 膨润土 (33.5 m2/g) 的比表面积增加了约 4 倍，而与正丁胺的相互作用导致酸活化膨润土的表面积减少了 40%，同时加宽了Si-O 拉伸峰在 1041 cm-1，d001 值从 14.5 降低到 13.5 Å。热分析数据证实了介孔正丁胺/酸活化膨润土复合材料在高达 499 °C 时的稳定性，然后在 500 到 700 °C 之间裂解层间正丁胺物质。
